The mail Does Not Send At All when using the alerts or the Macro. I wish to send it to anne.e.duffy@123.ie

The reason why I was showng you the user preferences was that the Test button on the mail works, so presumably I have the correct information set up.

The EMail address that I loaded into the script was copy and pasted excatly from the user preference set up so I do not understand why it will not send the mail when I press the button , unless there is somewhere else I need to update.
